You can now reconnect power, turn the printer on and start printing with your direct drive printer!
You should optimize a printing profile to the printers new configuration – you can usually get away
with a significantly reduced retraction compared to when you used the Bowden setup.
Troubleshooting
If temperature measurements are incorrect or if the hotend does not heat up then the thermistor
cable or heater cartridge cable may have been damaged or come unplugged. Examine the cables to
see if this is the case.
If the extruder motor does not move the extruder gear, then one, or both, ends of the NEMA motor
cable may not have been connected properly (see steps 22 and 28).
If you cannot get the extruder to push filament through the nozzle, then it is likely that the short
PTFE tube has not been inserted properly (see step 9), or that debris was not cleaned out of the
hotend heatsink when you removed the Bowden tube. This can also be due to the small PTFE tube
having been damaged during insertion, if this is the case you should cut a new piece of PTFE tubing
to the same length as the damaged tube ~61mm.
